BULK ROOF' STOCK RECO'ILER 4 shets-sheet :s

Filed Jan. 13, 1961 ATTORNEYS May 12, 1954 R. F. TOLL BULK ROOF STOCKRECOILER Filed J'an. 13. 1961 4 Sheets-Sheet 4 United States Patent()3,132,820 BULK R001? STSK RECOILER Richard F. Toll, '7400 Kanis Road,Little Rock, Ark. Filed Jan. 13, 1961, Ser. No. 82,454 Claims. (Cl.242-611) The present invention relates generally to a stock recoilingmachine or recoiler. The machine is particularly adapted to handle largebulky types of material such as rooting for house trailers, and thelike.

In the past, aluminum roong for house trailers has been fabricated andwound on spools for shipment to customers. This aluminum material isgenerally .020 of an inch which is joined by a caulked cap strip forminga onepiece roof approximately 10 feet Wide by any desired length. Thecustomer uncoils the material from the coil and cuts it into variouslengths, as required, in the manufacture of house trailer roofs.

Prior to the development of the recoiler, the spool of roofing wasplaced on a frame With an arbor shaft at each end which were insertedinto the hub of the spool. The material carried by the spool was thenpulled out on .a low, long table or on the ground at which time thematerial was measured and then cut to length. After the piece ofmaterial was cut from the spool it was then recoiled into a smallerdiameter coil for ready handling and subsequent installation on thetrailer roof. It was foundrthat the pulling olf of a piece of materialfrom the spool in the manner described above was a very cumbersome andawkward operation that required four to ve men to do the job. On a windyday sometimes the piece of metal would be extremely diflicult to handlefor in some cases lengths of sixty feet are required.

The newly developed recoiler now makes it possible to accomplish theoperation of cutitng a strip from the spool with only one man, in afraction of the time required with the old method. The roof is alsobetter protected from damage of the type that has occurred in the pastfrom men stepping on the roof while it was on the ground. The roof isalso now better portected from Wind damage and the like.

The recoiler is portable and can be moved from place to place, and inmany instances can be located next to the assembly line rather than insome remote location. The present recoiler is of the type that occupiesless than 60 square feet for its use.

An important object of the present invention is to provide a recoilerwhich is capable of handling large bulky pieces of material with aminimum of effort.

Still another important object of the present invention is to provide anew and improved recoil spool-like structure which may be readilybroken-down so the material recoiled may be removed from the recoilspool-like structure and its components may then be reassembled soanother piece of material may be cut and recoiled;

An important feature of the present invention relates to the provisionof discs and disc pins as well as a removable break-over bar disposedbetween the discs to eliminate the necessity of a continuous arborjoining the discs and extending through the center of the coil of thespoollike structure for recoiling the material to be recoiled.

Yet another important feature of the present invention relates to theprovision of a break-over roll disposed between the main spool and thespool-like structure for recoiling, which break-over roll operates toproperly support and arch the sheet metal material which is to berecoiled.

A still further important feature of the present invention relates to asupport structure for the coil of recoiled material which structureoperates as a brake and further functions to receive the coil after discpins carried by 3,132,823 Patented May 12, 1964 the discs have beendisengaged from the coil of recoiled material.

In accordance with more speciiic features of the present invention,there is provided a stock recoiler for trailer roofs which includes aframe. A main spool is journaled on the frame. Releasable main spoolbrake means is carried on the frame for preventing the spool fromrotating. A support or break-over roll is journaled on the frame at Yoneside of the panel for arching the material as it is drawn from the mainspool. A spool-like strucl ture is provided for coiling a length ofmaterial cut from the main spool into a sub-coil including a pair ofsub-coil discs journaled on the frame adjacent the break-over roll. Thesub-coil disc cooperates to provide a rewind coil or sub-coil on whichmaterial is wound from the main coil. A break-over bar is connected toand between the sub-coil discs. Clamp means is carried on the break-overbar and the discs for attachment to an end of a piece of stock stretchedfrom the spool over the break-over roll. Means is connected to the discsfor rotating the discs to Wind a length of material from the spool overthe break-over roll about the break-over bar. A sub-coil rest issupported on the frame which has means for moving the rest radially ofthe discs into and out of engagement with the sub-coil to facilitatecutting of the sub-coil from the main coil and to assist in the removalof the sub-coil from between the discs.

Other objects and features of the present invention will more fullybecome apparent in View of the following detailed description taken inconjunction with the accompanying drawings illustrating a singleembodiment and in which:

FIGURE l is a perspective view of a stock recoiler in accordance withthe present invention;

i FIGURE 2 is a side elevation of the stock recoiler; FIGURE 3 is an endelevation of the stock recoiler; FIGURE 4 is a perspective View of oneside of the recoiler; and i FIGURE 5 is an enlarged cross-sectional viewof a brake mechanism on the main snool structure.

As shown on the drawings:

The reference numeral 10 in FIGURE l indicates generally a stockrecoiler. The recoiler has a frame 11 which carries a main spool 12.Journal means 13 is'provided between the main spool 12 and the frame 11to permit the main spool 12 to rotate relative to the frame.

A spool-like structure or rewind spool 14 is disposed adjacent the mainspool 12 and journal means 15 is disposed between the structure 14 andthe frame 11 to permit the spool-like structure 14 to rotate relative tothe frame.

A spool of material 16 is carried on the main spool 12 which materialmay be of any suitable type such as aluminum. The spool of material 16has an end 16 to be recoiled on the spool-like structure 14.`

The frame 11 includes upright frame side members 17-17 suitably fastenedto an I-shaped longitudinal frame member 18. The side members 17-17include upright posts 19-19 and side frame portions Ztl-2t). The uprightposts 19*19 support the main spool journal means, while the side frameportions 20-20 support the journal means 15 for the spool-like structure14.

Secured to the underside of the I-shaped longitudinal frame member 18 isa jack or jack means 21. Any suitable number of jacks 21 may beprovided. The purpose of providing the frame 11 with a jack 21 is tosecurely rfasten the portablestock recoiler 10 to the ground so that asthe end 16 of the coil 16 is pulled away from the mainv spool 12, theframe 11 Will not move on its casters 22.

As illustrated, the jack is of the type that has a depressible footpedal 23 secured by linkage to a vertically movable ground engagingYjack foot 25.` When the operator wishes to prevent the portable recoilerfrom moving on its casters 22, the operator may apply pressure by meansof his foot to the depressible foot pedal 23 and thereby cause thelinkage to actuate the jack toot 25 until it engages against the ground.Secured to the linkage 24 is a foot release or irneans for collapsingthe linkage indicated generally at 26 which foot release operates toelevate the foot 25 to disengage it from the ground.

The journal means 13 include four bearing units 26 two of which aresupported on each of the upright posts 19-19. The bearing units 26 eachinclude a bearing housing 27 and a ring bearing 28. The bearing units 26support a pair of main spool supporting shafts 2.9-29 on the post 19.The main spool 12 hasV sockets for the receipt of the main spool supportshafts 29-29 enabling the main spool 12 to be rotated relative to theposts 19 on the ring bearings 28. It will be appreciated that anysuitable type of bearing structure may be used to support the main spool12.

Disposed at one end of the spool 12 is a main spool brake means orstructure indicated generally at 30. This brake structure 3th is shownin detail in FIGURE 5 and comprises a pair of lower and upper brakeplates 31 and 32. The brake plate 31 is suitably secured to the post 19.Supported on the brake plate 31 by a pair of threaded pins 3333 whichextend through the brake plate 32 is a crank support plate 34. It willbe noted the pins 33--33 have nuts 35--35 secured at the threaded endsthereof to clamp the crank support plate 34 on the brake plate 31. Ascrew 36 extends transversely through the crank support plate 34 and hasits free end engaged against the upper brake plate 32. The opposite endof the screw 36 is provided with a crank or crank handle 37. The brakeplates 31 and 32 are each provided with a suitble type of braking ringsegments '3S-38 which segments are adapted to engage about the mainspool support shaft 29. When the crank handle 37 is rotated in onedirection a braking force is exerted through the plate 32 and the upperring segment 34 to prevent rotation of the shaft 29. The brake may bereleased by rotating the handle 37 in an opposite direction.

Disposed between the main spool 12 and the subspoollike structure 14 isa support bar or rod 39 on which is carried a lineal foot counter 40 anda toggle clamp 41 Also disposed between the main spool 12 and thesubspool-like structure 14 is a breakover or support roll 42. The roll42 provides means for arching the metal in the winding of the materialon the rewind coil 14 to form a sub-coil or rewind coil. The break-overroll is supported on the frame by means of a pair of break-over rollsupport posts 43-43 which are secured to and extend above the side frameportions -20- It will be appreciated the break-over roll 42 is adaptedto rotate freely for the roll 42 has stub shafts 42a-42a which arejournaled on the break-over roll support posts 43-43 at 42b-42b (FIGURE2). These posts 43-43 also serve to support the bar or rod 39, which rodcarries the counter 4l and the toggle clamp 41. It will be noted the bar39 is disposed slightly vertically above the break-over roll 42 so thatthe free end of material 16' may pass therebetween. The toggle clamp 41serves to clamp the free end 16 of the material 16 against roll 42 toprevent the material 16 from uncoiling or spring back onto the mainspool 12.

The counter 40 may be of any suitable construction and the purpose ofthe counter is to measure the number of feet of material 16 that hasbeen taken from the mainy spool 12 and wound upon the spool-likestructure 14.

The spool-like structure 14 includes a pair of sub-coil or spool discs44-44 which are joined together by means of a break-over bar 45. Thediscs each have a series of circumferentially spaced annularly arrangedaxially extending, axially adjustable disc pins 46. Since each of thepins 46 is identical, a description of one will be adequate for theothers. The disc pin 46` includes a sleeve 46a which is iixedly attachedto the associated disc 44,

such as by a Weld or similar connection. The disc pin 46 is extendedthrough the sleeve 46a, through a hole in the disc 44, and then into anopen end 45a of the break-over bar 45. By using a break-over bar it isnot necessary to use a center arbor on the spool-like structure 14 andthe advantage of this is that the recoil material may be readily removedfrom the spool-like structure 14 so that the spoollike structure 14 maybe reused without having to supply a spool for each of the recoiledlengths of material.

It will be noted that a series of pins 46 are provided on the discs.While a pair of the pins serve to hold the break-over bar in assemblywith the disc, the other pins cooperate with the break-over bar inproviding the spoollike structure with arbor-like means upon .which thematerial may be recoiled. All of the disc pins `46 function in the'sameway and when it is desired to coil material upon the spool-likestructure 14, the pin elements or portions 46 are extended through theplates or discs 44 so that the material may be wound about these pins.To assist in the winding of the material about the spool-like structure14, a series of C-shaped clamps 47 are welded in assembly with thebreak-over bar. ln operation, the end of the material on the main spool12 is manually drawn between the bar 39 and the break-over roller 42 andthe C-shaped clamps 47 carried by the break-over bar are clamped to thefree end of the material so that when the discs 44 are rotated thematerial may be wound about the pins 46.

Supported upon the side frame portions Ztl-20 is the journal means 15which includes T-shaped spool-like support columns iS-43. Each of thecolumns has a tubular sleeve 43a which is in coaxial alignment with theaxis of the discs 44-44. The sleeves 48-43a have a rotatable sleeveshaft 48b extending therethrough with a sprocket 48C secured to an`outer end of the sleeve shaft 4817 and a lgear `48d secured to anopposite end of the shaft 48h. The gear 48d is lixedly attached to oneof the discs 44. Fixedly attached to the sleeve 43a is a second sleeve49. A shaft 50 is carried lwithin the sleeve and it has a pinion gear 51carried on one end which pinion gear is in mesh 'with the pinion 48d.Connected to the opposite end of the shaft Sil is a crank 4handle 51. Itwill be appreciated that by rotating the handle 51', rotary motion maybe transmitted to the pinion gear 51 which in turn will cause the gear48d to turn at low speed with high torque to rotate the disc 44. Powertransmission means is provided for transmitting the force which isapplied through the crankhandle 51 to the disc 44 so that the disc 44 atthe opposite end of the machine may be simultaneously coaxially rotated.A'Ille power transmission means is indicated generally at 52.

From an examination of FIGURE 2 it will be seen that both of the discs44 are supported and journaled upon the side frame portions 29 in anidentical manner. As described above, the discs are both supported upona T-shaped spool-like support structure 48. The structure 48 includesthe sleeve 48a and the sleeve shaft 48b which is journaled in the sleeve48a and is xedly attached to the associated disc 44. l'lne opposite endof the shaft 48b is provided with the sprocket 48C.

The power transmission means includes chains 53-53 which are supportedat upper ends by the sprockets 48e. A tubular column S4 is joined atopposite ends with the side frame members Ztl-20. Contained within thetubular column is a power transmission shaft 55 which carries a sprocket56 at -its opposite ends. The chains S3 are connected at the oppositeends thereof with the sprockets S6. Thus, when the crank handle 51 isrotated, the sprocket 48e, at the crank handle end of the machine, iscaused to rotate and the chain 53 is actuated. The power of the chain istransmitted through the sprocket 56 and lthe shaft S5 to the disc 44 atthe opposite end of the machine. At the opposite end of the machine, asimilar chain and sprocket vdrive is utilized to rotate the disc 44.

The spool-'like structure is provided with a crank brake 57 which may beturned into engagement with the crank shaft 50 so that the discs 44cannot rotate.

In order to assist in the Winding of the sub-coil or rewind coil uponthe spool-like structure 14 and also to assist in removing the sub-coilfrom the spool-like structure 14, the machine is provided with asub-coil rest structure indicated generally at 66. The structure 60includes two pairs of pads or rests 61 each of which is provided with aseries of teeth for -gripping the sub-coil. The pads 61 are providedwith means indicated generally at 63 for actuating the pads radially ofthe sub-coil. The pads 61 of each pair are joined together by a Y-shapedpost member 64 which includes 'a vertically extending shaft 64a. Mountedupon the horizontal column 54 are a pair of rest support sleeves 65 andthe shafts 64a are engaged within the sleeves 65. Each of the sleeves 65has a side slot 66 and a cam 67 is pivotally mounted in the slot. Thiscam is adapted to engage the end of the rest shaft 64a of the postmember 64 so that the rests or pads 61 may be moved vertically up anddown.

A cam actuating structure 68 has been provided for operating the cams`67. 'Ihe cam actuating means or structure 68 includes lever arms 69 and71 and link 7d. The lever arm 69l is pivotally attached to the post 43at 72. The lever is adapted to be moved back and forth between lever armguides 73-73. The lever arm 69 also carries a cam lever brake 74. Thebrake 74 includes la threaded pin Iwhich extends through the cam leveror arm 69 by turning the handle end 74a `of the brake to cause theopposite end to be engaged with the cam lever Iguide 73 when the arm 69is to be braked. It is in this way that the movement of the cam lever 69may be restricted.

The lower end of the cam lever 69 is pivotally connected 'With the link70, as indicated at 75. The opposite end of the link 70 is pivotallyconnected to the lever arm 71, as indicated at 76. A cam actuating rockshaft 77 extends transversely of the machine in parallel alignment withthe transverse power transmission sleeve 54 and is secured to each ofthe cams 67. The rock shaft 77, at one end, extends through the sideframe portion and is connected to the lever arm 71. The lever arm 69 and71 extend in opposite directions with respect to the link 70 which joinsthe lever arms 69 and 71 together. When the cam lever 69 is actuated,the lever arms 71 are also actuated and the rock shaft 77 is rocked tocause the rest pads 62 to move into and out of the engagement with thecoil carried between the disc 44.

The rest pads serve not only as a brake but also as means to receive thecoil after the disc pins 46 have been disengaged from the material whichhas been recoiled.

Operation A spool of material is initially mounted on the machine 10.The free end of the material is pulled between the toggle clamp supportbar 39 and the break-over roll 42. During this operation, the spool 12is braked by the main spool braking means 3l) to adjust the tension ofthe coil as the material is drawn from the main spool. The C-shapedclamps 47 are secured to the free end 16' of the length of material 16and the crank 51 is turned or rotated to cause the disc 44 to rotatewhereupon the material is Wound about the disc pins 46.

Before the material is wound about the spool-like structure 14, thecounter is placed into position and engaged with the length of material16 adjacent its free ends 16. The crank brake 57 is then locked toprevent the sheet from turning the disc 44 and the toggle clamp 41 isreleased. The operator now places a slight strain on the crank handleand releases the crank brake 57. The crank 5l is then turned and thesheet material is coiled about the spool-like structure 14. The operatorcontinues to turn the crank until the desired number of feet register onthe counter 4i).

The operator then stops turning the crank 51, he locks the spool brake37 and he operates the cam actuating mechanism 68 to cause the cams 67to actuate the rests 62 to hold the sub-coil or recoiled length ofmaterial in position. The operator then locks the toggle clampv 41 and,by means of a chalk line, he then marks the material for cutting. Thematerial is cut by means of a shear or any other suitable means. Theoperator then releases the cam lever mechanism 68 by releasing the brake74 and the operator turns the crank 51 until the cut edge of material isnear the rest pads 61. The cam lever 69 is then locked by turning thecam lever brake 74 to hold the cut edge of material while the length ofrecoiled material is banded. Suitable types of steel bands may bewrapped and secured in circumferential engagement with the sub-coil tomaintain'the material in a coiled position. y

The cam lever brake 74 is then released and the disc pins 46 are pulledout of engagement with the recoiled material so the material or sub-coilmay drop onto the rest pads 61. The break-over bar 45 is then removedfrom the sub-coil by disengaging the C-clamps 47 from the inner ends ofthe coil. The break-over bar 4S is then replaced in the machine and thedisc pins are again extended through the discs so another length ofmaterial may be taken from the main spool Wound'upon the spoollikestructure 14 to form additional coils.

It will be understood that modifications and variations may be effectedWithout departing from the scope of the novel concepts of the presentinvention.
